Can you use compression fittings on soft copper?
“Soft” copper can also be joined by soldering or brazing, and is also connected using flare-type or compression fittings. Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe (Photo 3). Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak.
How long do braided steel supply lines last?
How long do stainless steel braided hoses last? Stainless steel braided hoses last at least five years. According to most manufacturers, you should replace them twice per decade.
Is a ferrule the same as a compression fitting?
In small sizes, the compression fitting is composed of an outer compression nut and an inner compression ring or ferrule (sometimes referred to as an “olive”) that is typically made of brass or copper or steel. Ferrules vary in shape and material but are most commonly in the shape of a ring with beveled edges.
How are compression fittings attached to copper pipe?
The valve (or other part) has a port where the pipe slips in, and the port has male threads on the outside. Before you fit the parts together, you slide a compression nut and a compression ring onto the end of the pipe. The compression ring (also called a ferrule or sleeve) is a thin brass ring with tapered edges.
How does a compression outlet for brass work?
Compression outlets typically consist of the pipe, a nut, a compression ring and the fitting itself. The nut and ring are placed on the pipe, then the fitting is placed at the pipe’s end. As the nut is tightened against the fitting the brass ring is deformed against the pipe itself, creating a strong seal.
What do ferrules look like in compression fittings?
Symmetrical ferrules look like two cones back-to-back, and can be placed into the fitting body in either direction. This increases the ease of assembly in applications where many fittings are used, and assembly time is critical.
Can a compression fitting be used on a gas line?
Never use compression fittings for gas-line connections. A compression fitting is not a specific plumbing part but rather a type of fastening system for valves, water supply tubes and other plumbing fittings. The valve (or other part) has a port where the pipe slips in, and the port has male threads on the outside.
What are the compression fittings for copper tubing?
These fittings include a nut with two sleeves (ferrules) for extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. Fittings are brass for good corrosion resistance.

Why are compression fittings made with two sleeves?
A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications.
How do you put compression nut on copper pipe?
Clean the outside of the pipe with a rag; it must be clean, with no paint or other contaminants. If necessary, apply a cleaner or solvent to the rag to clean the pipe. Slip the compression nut from the compression fitting onto the pipe, then slip on the compression ring. Slide both pieces down so they are 1 inch or so from the end of the pipe.
